The client sets both the name of it's private queue in the reply-to
field and and creates a unique correlation id for each RPC. So all the
"server" has to do when responding is to a) set the routing key of the
message to the value of the reply-to field it received on the inbound
message and b) copy the correlation id from the inbound message to the
resulting outbound message. There are examples of how to do this in
the Erlang, Java and .NET clients - just look for modules/classes
called RpcServer.
